Mark covered it well, and you should see some black smoke out the exhaust in your mirror under acceleration if it's running so rich that it's bucking.
A wideband AFR gauge kit will tell you your AFR's when it's calibrated and in a good mood...

If you have oil spray leaking out of the charge pipe orings like you say then it sounds like the compressor side turbo seals are getting tired and starting to leak a little along with metered air leaking under boost pressure which will cause a rich mixture.

I'd also suggest you send your WUR to Brian Leask and have him make it adjustable, then it's really easy to dial it in exactly how you want it while keeping things simple.
Brian Leask is very personable and helpful to talk to and his turnaround time is fast.
